BOMB.

Application mea March i7, 1919. serial No. 283,073.

To all. whom t may concer/1t:

Be it known that 1, MAURICE VETZEL, a citizen of the United States, residing at Spring Lake, in the county of. Ottawa and State 'of Viehigan, have invented new and useful Improvements in Bombs, of which the following is a specification.

The present invention relates to bombs, such as are used for spectacular and for advertising purposes, and one of its objects is to provide a bomb of that character improved in various features of construction; a further object is to provide such a bomb, one part of whose walls is adapted to burst more readily than another; a further object is to provide in such a bomb means for preventing advertising rmatter and the like therein contained from injury arising from ythe bursting of the bomb.

These and any other objects hereinafter appearing are attained by, and the invention iinds preferable embodiment in, the structures hereinafter particularly de scribed and illustrated bythe accompanying drawings, in which: w

Figure 1 is a central longitudinal section of a bomb ofthe character described, cer

tain parts being broken out; j f p Figure 2 is a transverse section of the same taken on a plane corresponding to line 2--2 of Figure 1, the envelope and binding cords being removed; A

Figure 3 is a top planvviewnf the'same, the envelope being removed;

Figure 4 is a top view of the side wall, vthe flaps of the same rnot being bent over; and Figure 5 is a fragmentary viewof a modi tied form of the bomb-s bottom wall, etc.

1n the embodiment of the invention chosen for illustration by the drawings and for detailed description in the body of this speciieation, the cylindrical bomb shown in Figures 1, 2, 3 and 4 has the top end wall desig nated generally l, the bottom end wall designated generally 2 and the side wall 3. This side wall is composed of two plies ot' suitable material, as paperboard. At the upper end of the side wall, both plies are slit to form flaps, the flaps' 4 of the outer ply 5 being in staggered relation to the flaps 6 of the inner ply 7, as particularly shown in Figure 4. The flaps 4 are folded over and securely fastened as by gluing to the member 9 of the top wall, and the flaps 6 are folded over the lower member 8 of the top end wall and are securely fastened as by gluing to andbetween the lower member 8 and an upper member 9 of the top end Wall, thus breaking joints kbetween the flaps of the two plies as particularly shown in Figure 2. lin order that the joint between the side wall and the rbottom endl wallmaybe i more frangible than that between the side wall' andthe top end wall '(for the reason hereinafter given), the inner ply is .not provided with flaps at its bottom, the flaps 10 of the' outer ply' however being bent over and may be fastened as by gluing tothe member 11 of the bottom end walh Outer members 12 .of the top end wall and 13 of the ,bottoni endwall are'A providedwith pe'- ripheral notches 14 uniformly spaced apart. The walls are securely bound together by a cord 15 seated in these notches andtightly wound around the bomb across and .parallelly between the ends and outside the Iside fw'all. A suitable envelope 16 tightly surrounds the 1 walls and cords, being glued in place, and forms a chamber 17 beneath the bottoinwa'll wherein is contained the'iiring charge 18 'oi .the bomb, which is'ignited by lighting the end l19 of thefuse 20 whenthebomb is inserted into the firing mortar.

Ina chamber 21 in the kbomb suitable ad.-` vertising matter` por; a floatmay Abe con# tained, to be released by the bursting of the bomb in the air. Beneath' a partition 22 the bursting charge 23 is contained in the' chamber 24, which charge is ignited by the slowtfuse 25, which is-ignited by the tiring i charge. Suitable vpackingi26 (as sawdust) may be' placed onthe .top of the partition i. 22 and beneath the Hoat in the chamber 21 to protect the oat from injury by the ein plosion of the bursting` charge. To further insure the float against such injury, stop struts 27 extend in the chamber 21 between the inside of the top wall and the adjacent (upper) side of the partition, which hold the partition from being blown upwardly by the bursting of the bomb. Similar struts 28 in the chamber 24 extend between the bottom wall and the adjacent (under) side of the partition as shown. All these struts may be secured in position by gluing to the inside of the side wall.

It will be seen that when the bomb bursts, it bursts at the bottom, opening out somewhat like an umbrella to release the )floatl carried in chamber 21. The {ioat is thus not injured by such bursting. This burstbeing placed in that end or' the bomb which is remote 'from the float, the joint between the side wall of the bomb and the end wall adjacent the bursting charge being at least as frangible as the joint between the side wall and the top wall which is remote from the bursting charge. tainly effected by the first mentioned joint being distinctly more trangible than the second mentioned joint.

In Figure 5 a mo'diiied construction of the bottom end wall 2 is shown wherein this wall is irovided with a circular onen-V ing 115, large enough to readily supply therethrough the bursting charge to the chamber 24. This openingis stopped with a plug 4:6 having` an orice l? therethrough adapted to contain theuse 25. It will be seen that the bomb may be stored' and shipped without the bursting kcharge therein, and when it is desired to sini/plyA such charge the plug` may' beremoved and the chamber 2e iilled with the chargej after which the plug` with the fuse 25 inserted into itsorilice 4i? may be driven in tightly and secured in place as by gluinm The cord 15 crosses the lower endr wall in thesame manner as it ycrosses the upper end wallshown in Figure 3: so that no porscribed,

I claim: l

1. In a bomb oitA the chav acter' described; an end wall; a two-ply side wall having at its end flaps folded overV and fastened to rIhis end is more cer' i/iaseei the end wall, the flaps of one ply being in staggered relation to those of the other ply.

2. In a bomb of the character described; an end ,wall comprising two members; a two-ply side wall having flaps at its end, the flaps ot one ply being Jfolded over and fastened between said members and the flaps ot the other ply being folded over and tastened. to the opposite side of one of said members7 the liaps ot one ply being in staggered relation to those of the other ply.

3. In a bomb oit the character described; end walls; a side wall having` flaps at each end7 and comprising two plies between the flaps at one end and the `flaps at the other end, there beingtwo plies of flaps at rone end only, the liaps being folded over and fastened to the end Walls respectivelv, the flaps of one ply of the two-ply end of the side wall being in staggered relation to those of the other ply of said twoply end of the side wall.

4. In a bomb of the character described; end walls having peripheral notches; a side wall; a cord seated in the notches and wound. around the bomb between and across its ends and outside the side wall. t

5. In a bomb ol' the. character described; end walls having peripheral notches; a side wall; a cord seated in the notches and wound aroundthe bomb between and across its ends and outside the side wall; and an envelope enclosing the walls and the cord and con- MAURICE WETZEL.
